When I try to connect to MySQL, I get the following error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
It seems like this is a common error as I googled it and found a lot of responses. I tried a lot of the responses to fix it and here are the various error messages I receive:
When running service mysql start:

When running ps -ef | grep mysql:

I've tried purging MySQL and reinstalling it but I get the same errors every time.
Everything was working fine but I upgraded the Ubuntu Server software and things don't work anymore.
